This fixes a number of unrelated issues, grouped for convenience.
It merges the KoblitzCurve and Curve classes in crypto.secp256k1.curve. While Curve is a subclass of KoblitzCurve, KoblitzCurve uses methods in Curve, so they're not really independent. And KoblitzCurve is never used directly anyway.
The other issues are explained by comments in the diff.
